Not a big fan of either, but Superman was always going to be OP because of how many different iterations/reimagining there are of him. Goku has been a little more defined having less people change him due to him being much newer/etc. The main problem is that a writer could add any power to Superman with any comic they write, he could be given complete invincibility, the fastest speed fathomable -giving him a much better advantage. Not that it really matters to me, but I tend to prefer the character with the coolest hair so out of the 2 of them I'd probably root for Goku XD
